The wayside and onboard railway measurement systems of evopro Innovation enable railway operators to monitor continuously the physical condition of vehicles and tracks. The diagnostic systems increase the safety of railway and the efficiency of freight transport.


The ERDM240 is a dynamic wheel load diagnostic system (WILD) for mesurement of wheel load, axle load, wagon load and detection of wheel defects at traveling speed. evopro Innovation was awarded in Hungarian Product Prize in 2014, Innovation Grand Prize in 2015 for the development of ERDM system.

The eRTM is a wireless sensor network for monitoring the temperature of the railway track.


Benefits of eRTM

  • increase safety of railway by detection and prediction of buckling
  • avoid derailment
  • decrease the lifecycle costs of infrastructure
  • energy optimization for the track heater circuits
  • increase efficiency and availability of the infrastructure by localization of the speed limitation
  • predictive maintenance planning by modeling the thermal behavior of the track

eRVM - Railway Vibration Measurement system

The eRVM is a vibration diagnostic system measuring the three dimensional acceleration with high resolution and accuracy. The eRVM installed as a wayside monitoring system detects the wheel defects and other irregular condition of the passing trains. The ERVM installed onboard is capable to monitor the dynamic behavior of the vehicle components and the impact forces applied by the track on the vehicle or goods. The onboard intallation detects the derailment and dragging phomomena. Periodic survey of the same track sections enable to follow the degradation of the infrastructure. ERVO module

Benefits if ERVM

  • measurement of the dynamic forces in direction of the wheel, bogie or other components of the vehicle
  • dynamic modeling of the vehicle by instrumentation of wheel, bogie, car body
  • quality control for transporting special goods
  • axle counting
  • detection of wheel defects and bogie problems
  • measurement and monitoring the deflection of the track


eRCM - Railway Condition Monitoring service

The eRCM data service of railway condition monitoring enables the subscriber operator the continuous monitoring of the physical condition of passenger and freight wagons. The service is based on the measurement data recorded by the wayside diagnostic systems. The eRCM service identify the long term trends of degradation and the sudden changes in monitored diagnostic parameters.

Benefits of eRCM

  • increase the safety and avaialability of railway traffic
  • monitoring the condition of wheels, axles, bogies
  • automatic detection of fast changes in primer and derived diagnostic values
  • identify vehicles of unsufficient physical condition
  • increase efficiency
  • increase availability and utility by predictive maintenance
  • decrease lifecycle cost by optimizing the condition based maintenance process
  • support predictive and preventive maintenance
  • conservation of track system by monitoring
